Hi,
I am trying to do the following simple operation with sed, but it wouldnt work because sed doesn't allow me to use variables in the replace string. Anyway to do it ?
testvar="TestFilename.#.txt"
testdate=`date +%m%d%Y`
resultvar=`echo $testvar | sed -e s/#/$testdate`
Here $testdate in the expression fails.
Basically I want to replace the "#" with today's date.
Your help is appreciated ...
regards
-MVal

You forgot the terminate /:
resultvar=`echo $testvar | sed -e s/#/$testdate/`

Thanks vgersh99, putting the replace statement in double quote solves the problem..
Thank nails, yes I forgot the ending '/' also...
